What is the Most Common Color of Eyes?
The Worldwide Survey of Eye Color
In 2023, a worldwide survey was conducted to learn the most common eye color around the world. The survey asked over 4,000 people from various countries, “What color is your eye?” and the results were surprisingly varied.
The Most Common Eye Color
The survey results showed that the most common eye color worldwide is brown. Approximately 79% of respondents had brown eyes, followed by blue eyes at 8.4%. Green and hazel eyes were each reported at about 5%, while gray eyes were the least common at 1.1%.
Eye Color by Geographic Location
When the survey data was broken down by geographic region, a few interesting trends emerged. For example, blue eyes were found to be the most common in Europe, while brown eyes were the most common in Asia and Africa. In the United States, brown eyes were the most common, followed by blue, green, and hazel.
The Science Behind Eye Color
Eye color is determined by a combination of genetics, environment, and pigment. The most common eye colors are caused by a combination of the two pigments melanin and lipochrome. Melanin is responsible for dark colors like brown, while lipochrome is responsible for lighter colors like blue and green.
Conclusion
The worldwide survey of eye color revealed that brown eyes are the most common, followed by blue, green, hazel, and gray. Geographic location also had an impact on the most common eye color, with blue eyes being most common in Europe and brown eyes being most common in Asia and Africa. The science behind eye color is complex and fascinating, and more research is being done every day to better understand why we have the eye colors that we do.
